Ingredients

Scale
  • 3 large egg whites or 4 tablespoons meringue powder
  • 4 cups powdered sugar, sifted
  • 1 teaspoon vanilla extract (optional)
  • 1/2 teaspoon lemon juice or cream of tartar (for stability)

Instructions

  1. If using meringue powder, whisk it with 6 tablespoons of cool water in a clean, grease-free bowl until slightly foamy. If using egg whites, whisk them until soft peaks form.
  2. Gradually add the sifted powdered sugar, one cup at a time, beating well after each addition.
  3. Add the vanilla extract and lemon juice or cream of tartar.
  4. Beat the icing on high speed for 5 to 7 minutes until it is very stiff, glossy, and holds firm, sharp peaks. This stiffness is key for construction.
  5. To use as glue, the icing should be very stiff. For piping details, you can thin slightly by adding a few drops of water until it moves slowly off a spatula.
  6. Work quickly when assembling your house, as this icing sets fast.

Notes

  • Ensure all bowls and beaters are completely free of grease or fat; this ruins royal icing.
  • For a whiter icing, use meringue powder instead of egg whites.
  • Store unused icing in an airtight container at room temperature for up to two weeks, pressing plastic wrap directly onto the surface to prevent a hard crust.
